Welcome, my name is***** am a verified expert automobile technician. I, and all others like me are neither employees nor agents of Just Answer.

I do my best to provide EXCELLENT 5 STAR service, please let me know what you need from me so you’re satisfied with my efforts and reward me with a Positive Rating.

I understand you have replaced all those parts, but I also understand sometimes we miss checking the simple things, such as making sure any alarm in the vehicle that will prevent the engoine from starting and running is disarmed. If the alarm is not causing the problem, then how about checking the four basic things an engine needs to start and run:

  • Compression should be at least 100 psi with less than 25% variation between cylinders
  • Fuel pressure should be 35-40 psi with key on engine off
  • Injector pulse Noid light plugged in any injector connector should flash brightly and steadily as engine is cranking
  • Spark should be strong at about 8-10 KW as measured with an ignition tester

TIP - if the engine starts and runs momentarily with starting fluid, compression and spark are OK

Can you check and let me know what you find so we can continue?
